WILLIAM M. PIATT, OF MAC-O-GHEEK, NEAR NEST LIBERTY, OHIO.

GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 510,989, dated December 19, 1893. Application filed June 23, 1891. Serial No. 397,237. (No model.)

Be it known that I, WILLIAM M. PIATT, a citizen of the United States, residing at Mac-o- ,Cheek, near West Liberty, in the county of Logan and State of Ohio, have invented certain new and useful Improvements in Grain- Binders, of which the following specification, taken in connection with the accompanying drawings, is a full, clear, and exact description, such as will enable those skilled in the art to which they appertain to make and use the same. I

My invention relatesto certain improvements and new arrangements of the devices set forth in my earlier United States Letters Patent, No. 276,458, of April 24., 1883; No. 367,441, of August '2, 1887; No. 374,267, of

December 6, 1887; No. 377,731, of February 7, 1888; No. 384,072, of June 5, 1888, and N01 415,124, of November 12,1889; whereby more satisfactory results are accomplished, and my invention consists of certain features of novelty which will be first described with reference to the accompanying drawings and then more particularly pointed out in the claims.

1 is the main frame of the machine constructed of steel bars, in substantially the manner set forth in my Patent No. 377,731,0f February 7, 1888, and 2 is the U-shaped drivewheel frame mounted upon the drive-wheel 3 by means of an axle 4. which is keyed to said wheel and journaled in the boxes 5.

The main frame 1 has an L-shaped side extension 1, and between this extension and the main frame, the U-shaped wheel frame 2 is pivotally attached at its rear points 2 2 by means of suitable pivot bolts which are journaled in suitable boxings formed at the connecting points of the two frames.

6, 6,'are two lugs formed on the front of the wheel-frame 2.

7 is the draft-tongue pivotally mounted upon the front of the wheel-frame 2 a short distance from its rear end by means of a rod 8 which is supported in the lugs 6, 6, and journaled in the boxing 9 bolted to the upper face of the tongue. This rod 8 is extended beyond the tongue at an angle therefrom and around the front portion of the frame nearly to the cutter bar, where at a point 10 in line with the pivotal points 2 2*, it is pivotally attached.

Thus it will be observed that the rod 8 is practically apart of the wheel-frame 2, and that said frame is pivoted to the main frame at 2 2" and 10.

11 is a brace rod rigidly secured at one end to the tongue 7 and provided at its otherend with an eye 11 which is journaled on the rod 8 outside of the outer lug 6. This rod 11 serves to brace the tongue on its pivot and prevent it fromsidewise movement.

Attachedto the inner side of the wheelframe 2 near the center is a double rack 12 (see Fig. XI) for'i egulating the position of the main frame and tongue with relation to the wheel-frame, and their heightfrom the ground. Attached to the corner of the main-frame 1 the upper end of this link the lever 14 is pivotally connected through a projection or arm 16 formed on said lever.

17 is a sliding pawl mounted on the tongue (and frame) and kept normally in engagement With the teeth of the rack by meansof a spiral spring 18 surrounding said pawl and impinging against a collar 17 thereon and a lug 17 on the tongue (and main frame) in a well known manner as shown in Fig. XI.

19 is alug formed on the tongue (and main frame) inwhichis pivoted an operatinglever 20 ,the lower end of which is pivoted to the sliding pawl at 21. To raise or lower the end of the tongue or the main frame on the wheelframe, oneset of levers 14 and 20 is grasped by the driver (which action disengages the pawl from the rack through the lever 20) and thepart raised or lowered by moving the lever 14 on its pivot.

22 is the grain-board and 23 is the grainwheel supported at the extreme left-hand side .of the machine. The grain-wheel is journaled in the outer end of the crank-arm '24, which crank-arm is keyed to a long shaft 25 which is journaled in the under side of the main frame and extends from one side of the machine to the other. At the right hand end of the shaft is keyed a crank-arm 26 extending at right-angles to the crank-arm 24, which crank-arm 26 is connected to an operating lever 28, by a pitman 29. (See Figs. II and IF.) The operating lever 28 is pivoted to the wheel frame ,2 and is provided with a spring pawl 28 and operating devices, which spring pawl engages in a rack 29 supported from lugs 30 projecting from the wheel frame. By this means the position of the grain-wheel 23 can be controlled and the height of the left hand end of the machine from the ground regulated.

31 is the finger bar in which reciprocates the toothed knife 32, which is operated by means presently to be explained.

33 is the drivers seat supported from the wheel frame 2 by a spring arm 34 rigidly attached thereto and curving up over the drive wheel.

By the arrangement hereinbefore described the driver in the seat 33 can regulate the height of cut from the ground and the elevation of the tongue to suit the varying conditions of the ground and-grain.

The main supporting drive wheel 3 is formed with an internal cog-gear 35 which gears with and drives the pinion 36 which is mounted upon a short cross-shaft 37 which is mounted in suitable journal boxings in the main frame 1 and wheel frame 2. The crossshaft 37 serves the double purpose of converting the motion from the pinion 36 and pivotally connecting the end 2 of the wheelframeto the main frame.

38 is a bevel gear mounted upon the crossshaft 37 and gearing with two bevel pinions 38 and 39. The pinion 38 is mounted upon a crank shaft 40 which is journaled in the support 41 extending up from the floor of the machine and carries atits other end the crank 42, to which is pivotally connected the pitman 43 which connects with the reciprocating toothed knife32. The pinion 39 is mounted upon a shaft 44 in line with and running in the opposite direction from, the crankshaft 40, and carries near its end asprocketwheel 45. This sprocketwheel 45 gears with the sprocket-wheels 46, 47, and 48, by means of the sprocket chain 49, for running the endless aprons, packers and cord-knottingmechanisms which will presently be explained.

The grain receiving platform is ahori zontal traveling endless apron 50, which is abroad ribbed belt, mounted upon suitable rollers which are journaled-in the frame. Adjacent to the inner end ofthe apron 50, so as to take the out grain therefrom, are two narrow smooth aprons 51, 52, preferably of three ply cotton, and slightly inclined from the receiving apron 50, back nearly to the bundle form'- ing said knottin g mechanisms. These aprons are set side by side, with a space between them, for the needle to operate in, and they are carried upon rollers 53,54, and 55, 56, the roller53 being thedriving roller mounted upon the shaft 58 which carries the sprocket wheel 46 at its forward end, from which it receives its power. The lower drums 54 and55 are mounted upon a common shaft 57 extending through both of them,which shaft is provided with a sprocket wheel 59 on its forward end in gear with, and driven from, a sprocket wheel 60, on the shaft 58 through the sprocket chain 61,whereby both of the belts are driven from the shaft 58. On .the other end of the shaft 57 is a sprocket-wheel 62, carrying a sprocket-chain 63 which gears with a sprocket wheel 64 mounted on the extended journalof the inner roller 50, whereby the receiving apron is operated.

The two narrow smooth aprons 51, and 52 serve as a traveling binder table, making a broad smooth surface extending on each side of the needle and being constantly moving straighten and prevent any possible lodging of the incoming grain, and assistthe packers above, and having smooth surfaces glide along beneath the grain freely while the needle is up binding the bundle, and assist in rolling the bundle out without allowing any obstruction tof orm in the throat of the binder.

65 is a suitable steel frame supported above and from the main frame by standards 66 and consisting of steel bars of substantially the same. construction as the main frame. This upper frame is formed substantially of an oblong shape with suitable cross bars for supporting the different operating parts, and

an arched portion to allow of the uninterrupted passage of the drive chain .49. V

67 are the packing devices, supported from the upper frame upon the shafts 68 and 69, the shaft 69 of which is extended to the front of the machine and is provided with a sprocket wheel =17 gearing with the chain 49, through which the packers are operated. The pack ers are constructed substantially the same as in my Patent No. 377,731, with a difiernce however in the mechanism for throwing them into and out of operating position. The track 70 is supported by the pivoted links 71 and is operated by a rod 72 which is pivoted thereto and pivotally connected to an operating lever 73,which is pivotally supportedfrom an upright bar 73 extending up from the upper frame; The end of this lever 7 3 normally impin gesagainst a pin 7 don the ejector wheel, (the construction and operation of which will be hereinafter explained) which holds the track 70'down and the packers to their work, but when enough grain has been fed for a bundle and the knotting'and ejecting mechanisms begin to operate, the pin 74 is removed from under the lever 73, and the tension of the packing belts elevates the track 70 which allows the packers to assume an inoperative position. After the bundle has been ejected by the rotation of the ejector wheel in the direction indicated by the arrow in Fig. IVthe parts are returned to their normal positions and the packers again thrown to their work by the pin 74 operating upon the lever 73.

75 is the binder stock rigidly mounted on the main frame at 76, and provided witha needle-shaft supporting arm 7 7, and a knotter shaft supporting arm 78, for supporting the needle and knotter in proper. relative positions.

79 is the butt-adjusting belt. It consists essentially of two endless sprocket chains 80, 80, mounted upon the sprocket wheels 82, 83

and provided at intervals with pairs of inwardly extending fingers Stupon which are pivotally supported the right-angled wings 85. These wings 85'are provided with sockets 86 into which the pivot fingers 84 are seated.

The pairs of sprocket wheels 82 and 83 are mounted respectively upon vertical shafts 87 and88, the shaft 87 being journaled at the bottom in a stirrup 89 and at the top in a bearing plate 90 attached to the under side of the binder shaft supporting arm 78, and the shaft 88 being supported at bottom in a bearing plate in the main frame and at top in the end of the supporting arm 91 extended from the upper frame 65.

- 92 is a board or track arranged on the inner side of the butt-adjusting belt 79, which is adapted to engage the heels 85 of the wings 85 and hold the blades out at right angles to the belt while they are on-their operative stroke.

Foroperating thebutt-adjusting belt, I provide the shalt t 58 with a bevel pinion 93, which meshes with a pinion 94 on the short shaft 95, which carries at its opposite end a bevel pinion 96 which in turn meshes with'a bevel pinion 96? on the lower end of the vertical shaft 87.

97 is the knotter shaft journaled in the arm 78 and boxing 97 of the upper frame, and having loosely. mounted on its forward end the sprocket wheel 4C8 which is kept constantly rotating by the sprocket chain 49. The binder shaft is only operated intermittently when a bundle is to be bound, and for this purpose I provide a clutch 98 keyed to the shaft 97, which is constructed and operated as fully described in my Patent 170.377.7231, of February 7, 1888.

Near the outer end of the shaft 97 is the kn'otter 99, which is supported in the hanger 100 which is loosely mounted upon the shaft 97 and anchored to the breast plate 101 by the rigid arm 102 secured rigidly to said hanger and said breast plate. The knotter is constructed the same as my knotter described and claimed in Patent No. 384,072, dated June 5, 1888, with the exception of the means for operating. 103 is the large bevel pinion which operates the gripper, and 104 is the small bevel pinion which operates the knotting bill which is of ordinary construction. These pinions are operated respectively by the mutilated gears, 105 and 106, the gears being so arranged as to rotate the knotter a whole revolution in one direction and the gripper a half revolution in the opposite direction, as fully set forth in my patent above referred to.

For intermittently opening the knotter bill I provide the following m'echanism:107 is an adjustable screw nut or collar working on the upper screw-threaded end of the longitudinally movable rod 108, and 109 isaswivel collar, resting on the gear 10aand secured to the upper end 107 of the tube or sleeve 107", which is jonrnaled inside of the gear 104;. A spring 110 surrounds the rod 108, and is confined between the nut 107 and collar 109; the nut 107 serving to adj ust its pressure for regulating the tension between the jaws of the knotting bill. Loosely mounted on the shaft 97 just inside of the'gear 106 is a hanger 111 in the lower end of which is pivoted a lever 112. Theopposite end of the lever 112 works in a cam groove 113 in the inner face of the gear wheel 105,and on the under sideof said lever is formed a socket 112 into which the upper end'of the rod 108 is seated, whereby the knotter jaws will be normally closed by the spiral spring 110, and will be intermittently opened by the lever 112 and cam groove 113.

a: is the gripper, and 'y is the cup-shaped the upper frame under the knotting mechanconnected to a pin 121 on t-hecrankarm 48 ism to keep the grain from interfering therewith, said breast plate ,beingprovided with a needle slot 114.

are the bundle ejector disks, each carrying an eccentrically mounted bundle ejector hook 116. Each of the ejector hooks is formed with a main armaand a heelport-ion Z). The disks 115 carrying the ejectors are keyed to the shaft 97 so as to rotate-therewith, and are so arranged with relation to the knotting mechanism that theyare thrown into operation just as the knot iscompleted. These disks are arranged to rotate in conjunction with cam tracks 117 hung from the upper frame 65, said cam tracks engaging the heel portions of the hooks and holding them to their work as clearly shown in the draw,- ings.

118 is the needle-shaft journaled in the arm 77 of the binder stock, and carrying at its rearend the curved needle 119,andat its for ward end an arm 120. Pivoted to this arm 1-20 .is a pitman 122 which is also pivotally which is keyed to the shaft 97, wherebyan intermittent oscillation is communicated :to the needle. As fhasbeenstated the needle is situated between the two grain feedingaprons, and isso arranged asto lay the cord for the for mation of a bundle and pass thecord to the knotting mechanism in the manner fullyset forthin my Patent No. 415,124, dated November 12, 1889. And similar to the arrangement in said patent I provide a link 123 pivoted to the needle and carrying a roller 124 in its free end. This roller runs on a track 125 which is slotted for the passage of the needle and link. This track runs from the edge Of the main frame over between the ends of the endless feed-aprons 51 and 52, where it drops down at .an angle of forty-five degrees to form an inclined portion 125 and passes off onto the bottom of the main frame. By this arrangement the link is not thrust up between the needle and incoming grain until just at the end of the stroke.

126 is the compressor arm and retaining finger. This arm is loosely mounted upon a shaft 127 which is'journaled in suitable lugs 128 formed on the curved breast plate 101, and said compressor arm 126 passes down through a slot in said breast plate in proper relation to the needle. 129 is a crank arm keyed to said shaft 127, and 130 is a spiral spring having one end secured to .the crank arm 129 and the other end adjustably connected to the compressor arm 126. The compressor arm is provided with a series of perforations 131 into which the right-angled bent end of the spring can be seated. By changing the end from one perforation to another the pressure of the spring 130 can be regulated. In the inner face of one of the disks 115 is a cam groove 132 (see dotted lines Fig. XIII) into which the crank arm 129 travels to intermittently raise the compressor-arm to extends up from the frame 65.

allow the ejector hooks to eject the bundle.

The object of providing a yielding compressor arm is to obviate the danger of putting too much strain on the needle bar at the moment of compression, andhy providing an adjustable spring pressure, the tension can be regulated to suit the size of the bundles required and the varying conditions of the 7 grain.

' The reelissupported and operated in the extending operating handle 136 and two rearwardly extending arms 137. In the ends of the rearwardly ,extendingarms 137 is mount- Gd the reel shaft 138 which carriesthe reel 139.

140 is theadjnsting mechanism, 141 is the vsliding collar and 142 theoperating lever for adjusting the reel abats, these parts beingcon- .structed in the same manner as fully 'described in .my Patent No. 374,267, dated De cember6, 1887. The operating lever 142 is pivotally supported upon an arm 143 which 144 is a .curvedsegmentbar orrack formed integral with the binder stock 75 and curving out over the sprocket wheel 48 between the reel supporting arms 134.

145 are cross-bars connecting'the arms 134.

146 is a sliding pawl working in loops 147 on ,the cross-bars 145, and engaging with the curved rack 144.

148 is a small bell-crank lever pivoted in one of the cross-bars 145 and having a slotted end which isconnected with a pin onthe upper end of the sliding pawl 146.

149 is a connecting rod pivoted to the bellcrank lever 148 and connected to .the bellcrank hand-lever 150 which is pivoted to the upper side of the handle 136.

151 is a collar formed on the rod 149, and 152 is a lug formed onthe reel operating handle 136 through which the rod 149 passes, and between which and the collar 151 a spiral spring 153 is seated which keeps the pawl normally in engagement with the rack. By this arrangement the reel can be shifted forward and back and its position with relation to the cutter bar regulated.

154 is a curved rack bar pivoted to the frame 65 between the arms 134, and passing up through a guide-Way 155 in the fork of the reel supporting frame.

156 is a sliding pawl supported in loops 157 attached to the under side of the reel-operating handle 136, and engaging in the rack bar 154.

158 is a connecting rod pivotally attached to the sliding pawl 156 and to a bell-crank hand-lever 159 pivoted to the under side of the handle 136.

V 161 is a lug formed on the operating handle 136, through which the rod 158 passes, and

is a collar formed on said rod, between which and the lug 161 a spiral spring 162 is seated to keep the pawl 156 normally in engagement with the rack 154. By this means the reel can be raised or lowered to suit the varying conditions of the grain.

On the inner end of the reel shaft 138 is keyed a cog-wheel 163 which meshes with a similar cog-wheel 16-1, which is keyed to a rotatable sleeve 165 journaled in the box 166 and on rod 168, and carrying atits inner end a bevel gear 167.

168 is a rod provided with an eye 169 near one end, one end of said rod being pivotally supported at 170 and the other end being journaled in the sleeve 165, so that it can oscillate to suit the changes in position of the reel.

171 is a bevel cog-wheel provided with a collar 172 which fits and rotates in the eye- 169 of the rod 168 and is retained therein by the flange 173. This bevel cogwheel 171 meshes with the bevel gear 167. On the forward end of the shaft 44 is a bevel pinion 174, which meshes with a pinion 175 on a cross-shaft 176 which is mounted in suitable bearings and carries nearits other end a bevel pinion 177.

178 is a stirrup having eyes 17 0 which are mounted on the shaft 176, said stirrup supporting at top a vertical shaft 180 by means of a flange 181 on said shaft. This shaft carries at its lower end a bevel pinion 182 meshing with the bevel pinion 177, and its upper end passes through the bevel pinion 171, and, through the spline 183 on said shaft and a suitable groove in the cog-wheel, rotates it. By this means the reel is operated to knock the grain over onto the receiving apron.

184 are lugs formed on the L-shaped extension 1 of the main frame 1, to which is pivoted the bundle carrier 185 consisting essentially of a bar 185 carrying a series of arms 185*. Rigidly secured to said bar 185 of the bundle carrier 185 is an arm 186 extending at right angles therefrom and to said arm 186 is pivoted apitman 187 which is also pivotally connected to the operating lever 188. The

engages in the rack 29. By this means the bundle carrier can be dumped at the will of the driver, the ejector hooks serving to throw the bundle from the main frame to 111160311161. Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

, 1. The combination of the broad ribbed apron 50, with the narrow smooth aprons 51, 52, substantially as herein set forth. I

2. The combination of the broad ribbed apron 50, with the narrow smooth aprons 51, 52, a needle and suitable knotting and operating mechanisms, as set forth.
